The objectives of this study were estimate of some Hematological and
Biochemical values and prevalence of iron deficiency among some Adolescent Girls
.The total sample included 489 female's student aged between 12-17 years was
chosen randomly from the middle schools in Gazan in Kingdom of Saudi Arabia for: 1. Study the nutritional status including evaluation daily food intake. 2. Laboratory investigations including evaluation level of iron, feriten, hemoglobin,
hematocrit and red blood cells. The results indicate: Data presented that the mean intake of protein, fat, carbohydrate, calcium,
phosphor and iron were less than recommended daily allowance for this sample. Also
the mean intake of energy was very less than recommended daily allowance. The
amount of vitamins also less than recommended daily allowance except niacin and
vitamin C were more than recommended daily allowance. The results showed that
there was a high significant between the amount of calorie intake and red blood cells,
hemoglobin and hematocrit also, was a high significant between the amount of protein
intake and red blood cells, hemoglobin and hematocrit .There was a significant
relationship between copper and hemoglobin, hematocrit and serum iron. There was a
significant relationship between phosphor and red blood cells, hemoglobin and
hematocrit. There was a significant relationship between vitamin A, hemoglobin and
hematocrit. There was a significant relationship between vitamin 812, red blood cells
and hemoglobin. Data of laboratory analysis showed that the means of hemoglobin for patients and
non patients were 11.0±1.2 and 13.0±0.69 respectively. The mean percent of
hematocrit was 33.48±3.19 for patients' girls than 38.00±1.S8 for non patient girls .The
mean iron serum for all patients was 1 O.80±S.67 than 15.7±5.29 for non patients. The
average ferritin content for all patients was 12.80±2.02 than 28.6±14.89 for non
patients .The results showed also that 8% of sample under study had hemoglobin
percent from 90-100% and the rest had hemoglobin percent less than 90 %. Results of laboratory analysis showed that 73.40% from age suffered from
anemia than 26.60%. The percent of prevalence of anemia was 56.4%as a result of
decrease hemoglobin, 59.9% as a result of decrease hematocrit, 69.5% as a result of
decrease red blood cell, 73.4% as a result of decrease cont of iron in blood and
47.8% as a result of decrees content of ferritin in blood. The results showed that there
was significant relationship between the age and the prevalence of anemia.
